the member for operating the clampingl mechanism being also shown aligned with but detached from said mechanism.

Figure 2 is an enlarged vertical section, on

the line indicated by 2 2, Eig. 1.

Figure 3v is a sectional view onf the line indicated by 3-3, Fig. 2'.

Figure 4 is a horizontal section on the line indicated by 4-4, Fig. 2,

Figure 5 is a sectional 5 5, Fig. 4.

There is. provided detail on the line a. pair of leaf-clamping members 13v of L-shaped construction, the longer leg of oneof the'y clamping members bein@ slidably conne cted with the. longer leg of the other clampingmember the sliding connection consisting ofv slots 14 Y in side flanges 15 of one vof 13 and studs 16 projecting the clamping members from flanges 17 of the other clamping member 13', said studs engaging in the slots 14'. The clamping members 13Y together constitute an adjustable binder back.

In. this instance,

the studs 16 are yieldingly vmounted so that they can be retracted from the slotsl in this instance, are attached to flat 14. The studs springs 18 secured to the `flanges 17 and pro- V jecting through holes 19 in the flanges 17.

The springs 18 yieldingly hold the studs in the slots and the flanges for the flanges l5 to slide in, thus 17 form channels making 'y a telescoping connection between the clampsupporting members LOOSE-LEAF BINDER.

ing members 13'. To separate the members, all that is necessary is to pull theV springs 18 outwardly to withdraw the studs' from the slots and' then slide the flanges l5 out of' the flanges 17. i 'A To the clamping members 13 are secured' the opposite ends of telescoping index guide retainingmembers 20 which `are adapted to extend through holes 21r formed in downwardlyextending tabs 22 of index guides 23. The binder back has intertting leaf'- 24, alternate onesl of said members being secured tothe different clamping members 13. Thus, the leaf-support is of sectional construction, one of the sections interengaging the other fand' said sections being,y in -slidable relation so that, when the clamping members 13 are slid in and out relative to each other, the leafsupport is contracted. and 'expanded accordingly. Preferably, the members 24 are provided on their upper faces with transversely extending grooves'25 so asto insure against slippage of the guides and leaves along said members when saidV guides and leaves are not tightly clamped between the clamping members 13. y

To force ther clamping members toward and Vfrom one another, there isv provided suitable means formed, in this instance, by a nut 26 and screw 27, the nutbeing secured in any suitable manner to onel of the members 13 and the screw .being rotatably supthe other clamping clamping member 29 through Said Y tending pin 30, the projecting ends of which.A

are adapted to be received in openings 311 in a' shaft 32,y said pins entering the openings 31 through slots 33. The shaftv 32 is thus detachable from the screw and can be readily turned by a crank-handle 34, so as to move the clamping members' 13 toward or from one another. Hinged at 35 to lthe clamping members 13 are covers or leaf supports 36. The foregoing will enable those skilled in the art to make and use the invention, and the operation may be briefly described as follows:

Assuming that the parts are in the positions shown in Fig. 1 of the drawings, it

will be readily understood that 'the binder may be opened the same as a book in order to inspect the mater on the loose leaves. It 1t be desired to unclamp the binder so that the leaves may be readily removed and replaced or new leaves added, in the operations ot bookkeeping, the operating member will be inserted through the opening 29 with vthe shaft 32 thereof engaged with the head of the screw 27, as in Fig. 2, and the handle 34: will be turned to openthe clamping members 13, thus sliding some of the leaf-supporting members 24 away from others of said members and at the same time moving the clamping members 13 away from each other. As this operation is taking place, the loose leaves A will assume the positions indicated in broken lines in Fig. 2, the bottom edges of said leaves resting in the grooves 25 and thus being prevented from slipping along the leaf-supporting members. This is very important, and no loose-lestl binder has preable leaf support in combination with an index-guide retaining rod. Thus, it is unnecessary to perforate or slot the loose leaves and the loose leaves are absolutely tree. when the clamping members are loosened and, accordingly, can be quickly removed and replaced in the binder. By not pertorating or slotting the loose leaves, one operation in the manufacture of said loose leaves is avoided and, also, the leaves are not so liable to be torn in the bookkeeping machine in which they are placed for receiving entries.

' In placing perforated or slotted loose-leaves in the bookkeeping machine, great care must be exercised to avoid tearing them and, accordingly, time is saved by use ot the unpertorated and unslotted leaves. rlhe indeX guide retaining rod anchors the index-guides in the binder and, accordingly, when said index-guides are tightly clamped against the loose-leaves, said loosedeaves cannot bulge and burst from between thee lamping mem-v bers as would be l were not securely anchored. In tact, it is impossible to even pull the `leaves out of the binder when it is closed.

It is to be understood that it is preferable to support the binder in a suitable tray and this binder has been shown in connection with a tray in our copending application for patent filed May 8, v1926, Serial No. 107,563, In the copending application, the binder is not only supported by the tray but coopH vlously'been constructed having an adjustl the case it the index-guides erates with said tray in a manner fully described in said application.v

As new leaves are added to the binder, said binder may be expanded by turning the shaft 32 so as to further space the clamping members 13.

At the end of a day or at any other desired time, after it is no longer desired to remove or replace the loose leaves, the shaft 32 will be operated to close the clamping members together and said shaft will then be detached from the screw 27 and the bind` er may then be pla eed in a vault or any other desired location.

It is to be particularly noted that by clamping the leaves with the means disclosed above, it is unnecessary to perforate said leaves as is the usual practice where Vloose leaves are held in a binder of this type.

The leaf-supporting members, it is to be noted, lie in a plane above the level of the telescoping index-guide retaining members 2O and the indexguides 23project below the level of said plane to engage the members 20 while theloose leaves rest with their bottom edges on the leat-suporting members and are thus held tree of the members 20.

We claim: 1. A loose-.leaf binder comprising clamp-- ing members, teleseoping index `guide retaining members secured at their opposite ends to the clamping members, and intertitting leaf-supporting members of which vseine are connected to one of the clamping members gud some toanother of the clamping memers.

2. A loose-leaf binder comprising slidablyv l connected clamping members,`telescoping index` guide members secured at their opposite ends to the clamping members, and a leafsupporting membersecured to one ci" the clamping members and lying lin a plane above the level of the guide members.

3. A loose-leaf binder comprising slidably connected `clamping members, telescoping indeX guide members secured `at their opposite ends to the clamping members, and leatsupporting members lying in a plane above the level of theguide members, alternate ones of said leaf-supporting members secured to the respective clamping members.V Signed at Los Angeles, California, this 29 day of April 192,6. i
